But one that makes me happy is Chīsana Bōken-sha" (ちいさな冒険者?, lit."Little Adventurer") performed by Sora Amamiya, Rie Takahashi, and Ai Kayano aka the Seeyus of Aqua, Megumin and Darkness.https://www.youtube.com/watch?v=cv4aH5Fg22s

I have listened to lots of songs that made me tear up, but none more so that Through The Years and Far Away in Voices of a Distant Star. That was such an emotional movie, and that song is really sad seeing how far those two are drifting.

The anime is not what makes this song sad for me. I associated this song with my recently deceased dog Kaly. Kaly was deftly afraid of thunder storms, and whenever she would panic I would sit with her in my walk-in closet, close the door, and play the song on repeat while I held her. Kaly was my best friend; we grew up together. I watched her die (she had 4 seizures in a row), and I played the song at her impromptu funeral. It's so bad that I can't even listen to the song anymore.

Flipping brilliant anime... Whenever this song played I'd be like YEAH THIS SHOW HAS SO MUCH BRO POWER. Swells my heart every time the electric guitar starts.

A lot of songs get to me actually, but only a few stand out immediately. Perhaps i'll edit in more later.

spoilers in my explanations

1. Tenshi ni fureta yo (K-On!)

A song that, to me, is close to the epitome of nostalgic sorrow. A "goodbye" said with a tearful smile. This song in particular stands out to me because it goes beyond the feelings of the characters and evokes the same feelings in the viewer for spending so much time with them. It may as well have been a song directed towards the audience.

2. Afterglow (School Live!)

This song, similar to the above, evokes feelings of nostalgia, but emphasizes sorrow over lost time rather than tearful reminiscing. The singer uses her voice to convey what almost feels like a sense of "grasping at the past", creating a strong sense of longing. However, I think the impact of the song is lessened without seeing the visuals as well, as there is something profoundly striking about watching happy memories literally fade right before your eyes.

3. Wings of relief (Madoka Magica Rebellion)

A song that evokes a feeling of true serenity and beauty. The song one hears as the eyes of the body close for the final time, and the eyes of the soul open for the first and behold the face of the divine. A piece that is simultaneously heartbreaking and indescribably comforting.
